Answer:
Genetic engineering has multiple applications in different fields. Genetic engineering is the process by which alterations are made at the genetic level so that the final product is superior in quality and yield.
Explanation:
Following are few of it's applications:
<u>Medical field</u>- Genetic engineering is been used to produce insulin artificially, human growth hormones, anti hemophiliac factors, vaccines and other drugs.
<u>Agricultural industry</u>- It has been used to synthesize improvised crops which give better yield and are pest resistant. E.g Flavr savr, a species of tomato which is more juicy and larger in size than regular tomatoes.
<u>Environment</u>- With the introduction of herbicide resistant corn, farmers reduced the use of tractors which in turn reduced the amount of greenhouse gases. Also, by imparting disease resistance to plants, a lot of plants are prevented from dying. In addition, the biodiversity of an area can be maintained.
Answer:
Option C
Explanation:
Miller and Urey performed an experiment, using some inorganic molecules such as water, methane, carbon dioxide and hydrogen in laboratories conditions similar to early earth conditions .
Amino acids molecules formed as the result of this experiment, this proved that small organic molecules such as amino acids are formed from inorganic molecules.
Hence, the correct answer is option C
